Native English Copywriter
If you're advertising to Americans, you need a copywriter who knows not only American vocabulary and grammar, but the expressions, idoms, slang, and culture of your audience. Because a copywriter who knows English "like a native" won't cut it, you need an American copywriter. That's me.
If you are reading this, you know English. If you know English, you don't need a translator. What you need is someone with the skills and knowledge to work with your internal marketing department to make sure your content evokes the desired response from an American audience. Someone to give your marketing an American voice. That someone is me.
